Do you know C macros?
Two implementations is switched by USE_SEMAPHORES.
#ifdef USE_SEMAPHORES
...
void
PyThread_free_lock(PyThread_type_lock lock)
...
#else /* USE_SEMAPHORES */
...
void
PyThread_free_lock(PyThread_type_lock lock)
...
#endif /* USE_SEMAPHORES */

When I try to understand the code about the thread. I found
the thread_pthread.h file has some duplicate functions. Like
`PyThread_free_lock`, `PyThread_release_lock`,
`PyThread_acquire_lock_timed`. IIUC, C doesn't support function overload.
So why we have functions with the same name and args?
